General Remarks: Definition and characters by Gerson & Davidson (1974).

Systematics: Greenoidea MacGillivray differs from Pseudomelanaspis Borchsenius by having pygidial lobes with parallel axes; from Crenulaspidiotus MacGillivray by lacking the small transverse furrow above the second pygidial lobes; and from Melanaspis Cockerell by possessing a reduced number of lobe-associated pygidial paraphyses (Gerson & Davidson, 1974).
